Packages that use OpenGL have NixOS desktop as their primary target. The current solution for loading the GPU-specific drivers is based on libglvnd and looks for the driver implementation in LD_LIBRARY_PATH. If you are using a non-NixOS GNU/Linux/X11 desktop with free software video drivers, consider launching OpenGL-dependent programs from Nixpkgs with Nixpkgs versions of libglvnd and mesa.drivers in LD_LIBRARY_PATH. For proprietary video drivers you might have luck with also adding the corresponding video driver package.
